This worksheet is designed to replace a lecture on the topic of ratios, proportions, and using the geometric mean in geometry.
I start out class with a 15-minute "mini-lesson," giving my students some basic examples of what today's lesson will be about. Once the mini-lesson is over, I have them get to work within their groups on this worksheet.
I use this activity within cooperative groups, and I circulate to make sure they are getting the purpose of the questions.
The file includes spiral review problems, and it also includes "reference" information in gray boxes, which I find helps students study for upcoming assessments.
This worksheet is intended to be written on directly.
Please download the pdf preview file first, so you can see exactly what's included; the product file is a word document, which you may personalize for your students.
Immediately before this worksheet, I use the worksheet named 'Simplifying Radicals for Geometry Spring 2014' (http://www.teacherspayteachers.com/Product/Simplifying-Radicals-for-Geometry-Spring-2014-1266656
), and immediately after this worksheet, I use the mini lesson named 'Using Similarity Spring 2014 Notes' (http://www.teacherspayteachers.com/Product/Using-Similarity-Spring-2014-Notes-1266689
